Grow lamps used to be massive and ungainly – fluorescent tubes more than a metre long that required complex and hideous systems of stands, cables and reflectors all coming at a significant price. They consumed a lot of power too, so not great for the planet, or your energy bills. They also emitted quite a lot of heat, raising safety issues and damaging the plants that were being grown.
Recent breakthroughs in LED technology have created a new generation of effective, cool-running grow lights that cost a fraction of the old-school options both to buy and to run, consuming up to 90% less energy. They have also reduced down in size, enough to be easily incorporated into average house decor, some seamlessly integrated into planter-cum-lamp designs. There is also increasing evidence to show LED lighting provides a significantly higher yield than traditional lighting.
Top 5 Benefits of LED Grow Lights
1. Long Life
In an environment where constant lighting is needed to make sure the plants can grow and flourish properly, lifetime is extremely important and of course, a long lifetime also allows for less frequent maintenance service time and costs.
LED lights have an incredibly long lifetime compared to other lights, often lasting for 10-20 years due to their high efficiency and low energy use.
2. Targeted Wavelengths
In order for plants of any sort to grow healthily in a greenhouse environment, the conditions therein need to be carefully regulated and controlled. Most importantly, they need to grow under the right temperature and light in order for photosynthesis to occur as naturally as possible.also allows for less frequent maintenance service time and costs.
Research has shown that plants are most sensitive to particular wavelengths of light and absorb the most chlorophyll when exposed to red and blue lighting colors. The highest efficiency of chlorophyll absorption occurs between 400 to 500nm and between 600 too 700nm, which is impossible to optimize using traditional HPS lighting where most of the light output falls outside this range. LED grow lights, on the other hand, can employ specific spectra to match these peak absorption ranges.
3. Energy Savings
A recent study of tomatoes in greenhouses revealed that for this setting, energy consumption can be decreased by up to 75% when compared to traditional lights. This means financial savings, increased efficiency and better for the environment.
4. Less Heat
LED grow lights have the clear advantage in comparison to other lighting methods in that it emits far less heat. This is of crucial importance for plant growth as too much heat can be very damaging to plants, decreasing growth and often leading to decreased life time.
5. Flexible Design
LED lighting has another significant advantage of being more flexible in design and technology compared to alternative lighting methods. For greenhouse lighting, this is especially important as different methods and placements can be employed for optimal lighting of the plants.
